If you have a degree with a major other than Neuroscience, you may need to complete a Diploma for Graduates (DipGrad) before starting postgraduate Neuroscience study. A DipGrad endorsed in Neuroscience will give you a background similar to that of a graduate with a BSc majoring in Neuroscience.
The DipGrad consists of seven or more papers, so it takes at least one year to complete. At least four of the papers must be at 300-level.
The papers that you take will depend on your background and your goals, and must be agreed in consultation with the Director of the Neuroscience Programme and the Director of the Diploma for Graduates.
The University of Otago's Diploma for Graduates page has more information about the DipGrad, and how to apply.
